Abstract
We developed novel nano-scale materials related to solar nenergy utilization under eco-friendly conditions from both theoretical and practical viewpoints. Firstly, we designed the CuxAgyInzZnkSm solid solutions customized with RuO2 or Rh1.32Cr0.66O3 co-catalyst display visible light driven catalytic activity for CO2 reduction to CH3OH. Secondly, we produced the nitrogen-doped graphene (NG) of high thermal conductivity by green ionic liquid electolysis for light emitting diode heat removal. Finally, we studied the farming way to extract the algal oil based on the novel material of cryptomelane nanowire.
